While a proper sat meter would be ideal, I in the interim propose you bundle together the 4922 with any of the affordable portable DVD players (about 3K to 5K), which sit comfortably atop the 4922, plus a length of electric cable and climb up the roof with the gear. I currently use the same and it does not disappoint. Indeed a press of the button on the blind search option as you slowly change the elevation and azimuth delivers fairly quickly. The beauty about this is that what-you-get-on-the-roof-is-what-you-get-in-the-house.
I personally find the usual meters very expensive for reasons I don't know, yet they are miniaturized versions of a screen and decoder together. Indeed a search on OLX and Jumia shows you will pay upwards of 14K for even the most basic ones like the Freesat V8 HD Satellite finder without a spectrum analyzer. Maybe the Li-Ion battery plus portability pushes up the cost
